As more Inhumans reveal themselves, more threats are going to come up. In “Marvel’s Agents of S.H.I.E.L.D.” Season 3, episode 14, a new group will try to take out the superpowered people, but they aren’t Hydra. Without Bobbi (Adrianne Palicki) and Hunter (Nick Blood) on the ABC drama, the team is shorthanded and might resort to some unorthodox methods of getting what they want.

The episode will introduce viewers to Ruben (Gaius Charles), Mack’s (Henry Simmons) brother. “When a radical group called the Watchdogs emerges with plans to eliminate the Inhumans, Agent Mack and his brother become caught in the crossfire,” the synopsis teases. Could Ruben be part of this terrorist group?

It looks like Daisy (Chloe Bennet) will do everything she can to take down this threat to Inhumans in episode 14, titled “Watchdogs.” She’ll use her powers to interrogate someone with connections to the group, but in the trailer, Mack doesn’t look thrilled with the idea.

Back in the lab, Simmons (Elizabeth Henstridge) will be making some interesting developments. “Meanwhile, Simmons discovers a powerful chemical compound that could alter the future for Inhumans,” the synopsis reveals. Earlier this season, Simmons discovered that Creel’s (Brian Patrick Wade) blood was essentially a cure for Inhumans. Will she figure out a way to use the blood for a cure that people could actually utilize?

She won’t just be in the lab this week. Photos show her during target practice, and it seems that being kidnapped by Hydra will make her want to be stronger than ever. “She’s going to try to arm herself,” Henstridge told Collider. “But it’s also a period of growth for her to realize that you make mistakes and you make decisions, in an instant. It’s another thing that she’s got to carry on her back.”

“Marvel’s Agents of S.H.I.E.L.D.” Season 3, episode 14 airs Tuesday, March 30, at 9 p.m. EDT on ABC.
